[4/4] selftests/sgx: Remove extra newlines in test output

The TH_LOG() macro is an optional debug logging function made
available by kselftest itself. When TH_LOG_ENABLED is set it
prints the provided message with additional information and
formatting that already includes a newline.

Providing a newline to the message printed by TH_LOG() results
in a double newline that produces irregular test output.

Remove the unnecessary newlines from the text provided to
TH_LOG().

Fixes: 1b35eb719549 ("selftests/sgx: Encpsulate the test enclave creation")

Sorry for the super slow latency. The reason has been job transition, and
also getting SGX remote attestation to work with a non-Intel stack.
